| Question 1: The Himalayas, the ________, and the Appalachians are prominent examples of compressional orogenies with numerous overthrust faults. | |||
|
|
| Question 2: Thrust faults were unrecognised until the work of Escher, Heim and Bernard in the Alps working on the Glarus Thrust, and Lapworth, Peach and Horne working on parts of the Moine Thrust ________. | |||
|
|
| Question 3: Duplexes occur where there are two decollement levels close to each other within a sedimentary sequence, such as the top and base of a relatively strong ________ layer bounded by two relatively weak mudstone layers. | |||
|
|
| Question 4: These conditions exist in the orogenic belts that result from either two continental tectonic collisions or from ________ accretion. | |||
|
|
| Question 5: The resultant compressional forces produce ________ ranges. | |||
|
|
| Question 6: Thrusts and duplexes are also found in accretionary wedges in the ________ margin of subduction zones, where oceanic sediments are scraped off the subducted plate and accumulate. | |||
